To review the possible uses of topical and systemic tocopherols as therapy for skin conditions in light of the widespread use of vitamin E by patients.
Index Medicus was searched for articles published from 1922 (when vitamin E was discovered) to 1966 (the beginning of MEDLINE). MEDLINE was searched for articles in English and French on vitamin E or tocopherol in relation to dermatology. Additional original articles were identified from the reference lists of the review articles.
Only well-designed controlled studies were accepted; anecdotes and open studies are cited for completeness and as direction for future research.
There was some weak or conflicting evidence that vitamin E is of value in yellow nail syndrome, vibration disease, epidermolysis bullosa, cancer prevention, claudication, cutaneous ulcers, and collagen synthesis and wound healing. It was of no use in atopic dermatitis, dermatitis herpetiformis, psoriasis, subcorneal pustular dermatosis, porphyrias and skin damage induced by ultraviolet light.
After 44 years of research there is still scant proof of vitamin E's effectiveness in treating certain dermatologic conditions. Further research in well-designed controlled trials is needed to clarify vitamin E's role.
鉴于患者广泛使用维生素E,综述局部和全身使用生育酚作为皮肤病治疗方法的可能用途。
检索《医学索引》中1922年(维生素E被发现的年份)至1966年(MEDLINE起始年份)发表的文章。检索MEDLINE中关于维生素E或生育酚与皮肤病学相关的英文和法文文章。从综述文章的参考文献列表中识别其他原始文章。
仅接受设计良好的对照研究;为完整性和作为未来研究方向引用了轶事和开放研究。
有一些证据薄弱或相互矛盾,表明维生素E在黄甲综合征、振动病、大疱性表皮松解症、癌症预防、跛行、皮肤溃疡以及胶原蛋白合成和伤口愈合方面有价值。它在特应性皮炎、疱疹样皮炎、银屑病、角层下脓疱性皮肤病、卟啉病和紫外线引起的皮肤损伤中没有用处。
经过44年的研究,仍然缺乏维生素E治疗某些皮肤病有效性的证据。需要在设计良好的对照试验中进行进一步研究以阐明维生素E的作用。
